Web :: Browser issues :: How to install multiple Firefox browser instances / versions ?

I'm on Windows. I try to install an old FF 1.0.6 to test a site with it. It prompts me to close the current FF (1.5.x) and I don't want to. I fear it has/will/would tamper with my nice current 1.5.x install.

is there a way to install many different instances side-by-side ?

Just shut down any instances of Firefox you have running and install in your new directory. You shouldn't need to install more than one 1.0.x version. There aren't going to be any differences as far as rendering goes.

Don't launch it yet.

You will need to create a folder for your 1.0.x profile. You don't want to use the same profile in both 1.5.0.x and 1.0.x. It could get mangled a lot and pose problems. Do not use any "profile manager" to do so.

Now create a shortcut to the 1.0.x firefox.exe and append this to the shortcut target: -profile "1.0.xprofile_folder"
It will look like "D:\Firefox 1.0.x\firefox.exe" -profile "D:\1.0.x Profile"

Always use that shortcut to launch your older version.

The first time you launch, a new profile will be created at that location. From then on, that profile will be used.

You won't be able to use both versions simultaneously unless you set the hidden environment variable MOZ_NO_REMOTE to 1. The easiest way to do this is with a batch file:

@echo off set MOZ_NO_REMOTE=1 start "" "D:\Firefox 1.0.x\firefox.exe" -profile "D:\1.0.x Profile"



Save as "Firefox_1.0.x.bat".

That will let you run your older version regardless of what other versions you have running. You won't be able to run two versions with the same profile at the same time, however.
